When two boats share the same hull type — in this case both the Kayot S225 O/B 2005 and the Kayot S260 2005 are modified vee designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

The power gap is worth calling out. Rated to 320 hp, the Kayot S260 2005 has a 95-hp advantage over the Kayot S225 O/B 2005's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Kayot S260 2005 carries 94 gallons versus 57 gallons in the Kayot S225 O/B 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Kayot S260 2005 is rated for 15 passengers, while the Kayot S225 O/B 2005 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Kayot S260 2005 could be the deciding factor.
